HAR'VESTER CUTTER-BAR.

SPECIFICATION forming part of Letters Patent No. 576,534, dated February9, 1897.

Application filed April 4, 1896. Serial No. 586,243. (No model.)

To all whom it may concern.-

Be it known that we, WILLIAM E. BALL and ALICE (J. BAILEY, citizens ofthe United States, residing at Zanesville, in the county of Muskingumand State of Ohio, have invented a certain new and useful Improvement inHarvester Cutter-Bars, of which the following is a specification,reference being had to the accompanying drawings.

This invention is designed as an improve ment on the cutter-bar shown inour Patent No. 540,623; and it consists in the peculiar constructionhereinafter described, and then definitely claimed at the end hereof.

In the accompanying drawings, Figure 1 is a perspective view of acutter-bar constructed according to our improvement. Fig. 2 is an endView of the same on a larger scale. Fig. 3 is a perspective view of acutter detached. Fig. 4 is an end view of a modification.

Referring now to the details of the drawings by figures, 1 indicates thecutter-bar proper, formed by bending a sheet of suitable metal twice,thus making three folds or layers of metal, 2 3 4, the last of which iscurved upward at the rear and then backward, forming an extended flange5, while the folds 2 and 3 form a deep groove.

Between the folds 1 and 2 are set the cutters 6 and the fastening-bar 7,which last is pivoted at 8 to the cutter-bar, so that said fastening-barcan be drawn out, as shown in dotted lines in Fig. 1, and when in thisposition the cutters 6 may be readily taken out. On returning thefastening-bar to the position shown in full lines and setting a screw orbolt 9 in the outer end the cutters, cutterbar, and fastening-bar areall securely fastened together.

The rear edges of the cutters are bent under, as shown in Fig. 3, so asto have an inturned flange 6, whereby they are made much stronger, asthe inturned flange is not so likely to flatten out as the single bendshown in our beforementioned patent.

The object of the flange 5 is to provide an extended bearing-surface inthe finger-bar to prevent the rocking of the cutter-bar when it is inoperation without adding materially to the weight. The upward turn ofthe metal between the lower fold and the flange materially helps tostiffen the bar.

The lower layer 4 of the cutter-bar may be. made separately-and rivetedor bolted on, as shown at 4 in Fig. 4, but we prefer to make it as shownin Figs. 1 and 2.

What we claim as new is- 1. A cutter-bar formed of three layers of sheetmetal, two of said layers having an opening between them to receive thecutters and the third layer extending rearward to prevent rocking whenthe cutter-bar is in motion, substantially as described.

2. A cutter-bar formed of sheet metal bent into three folds, one ofwhich extends in the rear of the cutter-bar proper to prevent rockingwhen in motion, substantially as de scribed.

3. A cutter-bar formed of sheet metal bent into three folds and havingits lower fold bent upward and then outward to form a flange,substantially as described.

In testimony whereof we affix our signatures, in the presence of twowitnesses, this 2d day of April, 1896.
